UNiTED vs'riasaisnr ROBERT E. LEE, OF AHILLSIDE, NEW JERSEY.

HOME TRAINER.

Application led September 10, 1925. Serial No. 55,453.

The invention is illustrated in the accom? panying drawing, in which Figure 1 is a side View ot' the device, showing the rear part of a bicycle in dotted outline. i Figure 2 is an end View of the device. Figure 3 is a detail view of a modified form oi -axle holding means.

rilhe device has a suit-able base, the form shownconsisting of parallel beams or stringers 10 held in substantially,parallel relation by the bolts 11 and having enough length to provide a solid and stable support. On the base is arranged a suitable frame which,with

the base, constitutes a stand for the rear wheel of a bicycle, the orm'shown consisting ot' uprights 12 extending' from each beam 10i/luid being held by braces 13 to provide rigidity to the uprights 12, the upriglits being adapted to receive the rear axle of a bicycle, the slots 14C in the uprights receiving the xle 15, the axle being held against ver-V tical niovcn'ient by suitable clamping means, .such as nuts 16.

The amount of exercise that the rider del srcs can be regulated so that the training can assume either straight smooth riding, or the pressure can be applied so as to provide exercise equivalent to hill climbing. To provide Jr'or this I employ a pair of rollers 17 which are adapted to be moved toward each other and held in such adjusted position, one being placed in rear of and one being placed in front of the central axis, or rather the plane of the axle ofthe rear wheel, one

i'orm of providing such adjustment consisting of the arms 18 which are provided with bearings 19 in which the axles 2O of the rollersv rotate and which are hinged at their other end so that they can swing, the bolts 11 providing convenient means for pivoting the arms 18 to the base.

The arms are connected Vbyrods 21 and a turnbuckle22 as typifying an adjusting means for drawing the Vrollers 17 `toward each other or forcing' them further apartr and holding them in such adjusted position.

It will be evident that with the axle 15.

iirinly held in position, drawing the rollers 17 toward each other willplace more friction on the tire of the wheel and thus in crease the exercise. j

In Figure 3 I. show a modified form of fastening means in which the upright 12 has a latch 23, the hook end 24 of which can be passed over the axle 15 of the bicycle when it is in the slot 14 and thus prevent any upward movement of the axle when an upward pressure is placed against the wheel by reason of the adjustment of the rollers 17. The latch 23 is hinged at 25 to the upright 12..

I claim:

1. A home trainer comprising a. stand ing means for securing the laxle of a bicycle wheel, arms pivoted tothe stand, rollers on said arms, and a connectionto hold the rollers at various adjustable distances apart to havv vary their pressure on the tire of the wheel.V

2. A home trainer comprising a stand hav-` ing means ior securing the axle of a bicycle wheel, arms pivoted to the stand, rollers o n said arms, and rods and a turnbuckle connecting said arms to force the rollers against the tire ofthe wheel.

3. A home trainer comprising a base, spaced uprights on the base, the uprights having vslots to receive the ends of the rear axle of a bicycle, arms `hinged to the `base so l
